Frequency analysis is of uttermost importance when dealing with controllability of a dynamic system in changing working domains. This becomes relevant due to the non-linearity in damping, stiffness and inertia properties of mechanisms with broad motion and under heavy external conditions, such as a motorbike running on off-road terrains, braking and transmitting traction to uneven road profiles. A relatively simple but complete planar model of the vehicle on uneven terrain has been here adopted, which takes into account the whole dynamics and non-linear rigid body kinematics of the motorbike. This complete planar model is the computational engine for running the eigenvalue analysis of the time-varying eigenproblem. Tracking the eigensolution variability along the working space becomes a relevant insight on the behaviour of the motorbike under the different conditions. Theoretical formulation and simulations are discussed in detail.

Abstract
Frequency analysis is of uttermost importance when dealing with controllability of a dynamic system in changing working domains. This becomes relevant due to the non-linearity in damping, stiffness and inertia properties of mechanisms with broad motion and under heavy external conditions, such as a motorbike running on off-road terrains, braking and transmitting traction to uneven road profiles. A relatively simple but complete planar model of the vehicle on uneven terrain has been here adopted, which takes into account the whole dynamics and non-linear rigid body kinematics of the motorbike. This complete planar model is the computational engine for running the eigenvalue analysis of the time-varying eigenproblem. Tracking the eigensolution variability along the working space becomes a relevant insight on the behaviour of the motorbike under the different conditions. Theoretical formulation and simulations are discussed in detail.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
